eBay would be a good place to check. I'm pretty sure you'll probably find a few lots with different stuff. Maybe write a nice letter to ST and they might mail you some back; they're all really nice guys!

just buy something from ST, they give me a shitload of stickers every time i order something from them....i have a stack of stickers that i don't know what to do with because i can't actually put them on my vinyl.
